Nectriaceae on dung

Re : Nectriaceae on dung
Hi Maren,
I don't know what that is, maybe a Nectriopsis but there is no known species of this genus on dung.
Asexual state on the perithecia seems acremonium-like, this character fits well with the genus Nectriopsis. Could you make a vertical section of the lateral, ascomatal wall and check the thickness?

All the best,
Christian

Re : Nectriaceae on dung
Hi Christian,
it was very difficult to get a fine cut of the wall, because it is very thin with 10 to 15 µm. I think there are max 3 cellayers in the wall. The color gets darker with age.

There are black dots on the substrate, so I think this species maybe is growing on old coprophilus pyrenomycetes. But I couldn't find fungal structures there.
Regards, Maren

Maren,
are you sure that the KOH is negative?

Re : Nectriaceae on dung
Christian,
I've checked the KOH-reaction again, there is no colourchange in KOH 3 %. I even tried a 20 % solution. The first image is in water the second in KOH 3 %.
